Better Characterization, Improved Yields & Higher OEE for Wafer Level Testing

Johnstech's IQtouch™ Wafer Test Solutions are based on a tradition of delivering innovative
technologies, while providing industry-leading final test expertise.

The new IQtouch™ Micro Final Test Probe Arrays, for example, deliver unsurpassed low and stable
contact resistance (CRES). This is accomplished through a balanced optimization among several
critical and competing engineered parameters, including effective test signal transmission path,
probe / wafer interface (“touch”) points and elastomeric web forces, and precision manufactured
components for superior X/Y/Z co-planarity
Engineering:

·    Industry’s Lowest CRES
·    Stable, Accurate Test Signals
·    Predictable Signal Length/Path
·    Elastomeric Web Force Control
·    Confident Characterization
Product Engineers and Test Engineers can now leverage a final test probe card array that provides lowest and most stable CRES on the market,
enabling accurate test results for the most critical test parameters on the most sensitive devices. Well-defined device characterization and
corresponding specifications will help differentiate your company’s devices in a highly competitive and fast-moving market.
Production Floor Test Managers will achieve higher production floor OEE across all of the wafer probing test platforms with reliably robust
technologies that quite simply deliver higher device first pass yields with more equipment uptime because probe cleaning requirements will be less
frequent.
Production:

·    Increase Yields, Less Retest
·    Less Cleaning, Simplify Maintenance
·    Reliable Probe/Elastomer Dynamics
·    Superior Co-Planarity and Witness Marks
·    Increase Operational OEE
